AW: Issue: svn:externals syntax does not accept -rHEAD

Hello Daniel,

>The update command accepts -rHEAD, but not necessarily -rHEAD plus peg revision. HEAD is a keyword for "latest in the repository", not "latest in the history of URL_at_REV". If an item has been deleted, it's no longer part of the >HEAD, as you've seen.

That is not the point. I did not state this. In the svnbook in the chapter regarding peg revisions you can find a clear statement that recreated objects on the same path are not the same things. That's why it's perfectly valid to ask "give me the HEAD version of an object existing @peg." And the result should be either
a) if the same object exist on HEAD on that path => give that object
b) if no object exists on HEAD that path => give me an error
c) if another object (recreated) after deletion exists on HEAD that path => give me an error

This is how svn checkout (svn co -rHEAD path_at_peg) works. I do not understand why I should not be allowed to advise svn:externals to do the same. Just to follow the specification of operating revision and peg revsions.

> It sounds like you want Subversion to search for the latest revision in the history of URL_at_REV. What if that item was deleted and later restored?

No. Not at all. Forward history of an object is another topic.

Wrong object? I just said that two objects on the same path are different to me. And I actually just want an answer on question "Does the file external path_at_peg exist on HEAD?". Answer: "Yes" or "No" or technically "object returned" or "error".

I cannot even answer this question with the given syntax. What is so difficult to allow -rHEAD on svn:externals?
